>>>   My Info:   Win7_64, Nightly 48, 32bit, ID 20160324030447
STR:
0. Open about:config , set pref "plugins.rewrite_youtube_embeds" to "false"
1. Open devtools, dock it to the bottom side of window, close devtools
2.A) Open "data:" URL in the form above in a new tab
2.B) Open http://dagobah.net/flash/internet_trailer.swf in a new tab
3. Press Shift+F7 to open Style Editor
4. Hover mouse over the resizer of devtools, hold left mouse button, move mouse pointer
   to the up by ~10px, release left mouse button, move mouse pointer to the bottom by ~10px

AR:
 A) After Step 3 Flash disappears
 B) After Step 4 Flash disappears

ER: 
 Flash plugin shouldn't disappear

Notes:
1) Nightly 2015-01-01 had none of these issues.
2) If I disable APZ, it fixes scenario (A)
Jim, I'm assuming this is behaving as you'd expect

Well, there're scenarios A and B. In each scenario you perform Steps 3-4 in the tab from Step 2

STR_A_simplified:
1. Open about:config , set pref "plugins.rewrite_youtube_embeds" to "false"
2. Open "data:" URL in the form above in a new _selected_ tab
3. Press Shift+F7 to open Style Editor

STR_B_simplified:
1. Open http://dagobah.net/flash/internet_trailer.swf in a new _selected_ tab
2. Press Shift+F7 to open Style Editor
3. If Flash is visible, resize devtools to the up a bit

I personally think this is the same breakage as bug 1242273 with simpler(?) STR

I'm not reproducing on win7. Tracy can you try?
Flags: needinfo?(twalker)
I can reproduce on Win7. For both samples in step 2a/b, once I load the Style Editor the Flash plugin disappears (the frame is still visible). Click in Devtools to make the the plugin reappear.

tested on:

Win 7, Nightly 48.0a1 20160324030447 - Reproduced.
Mac, Nightly 48.0a1 20160328030215 - WFM 
Ubuntu, Nightly 48.0a1 20160325030241 - WFM

We could still take a patch for this in beta, but I think it is reasonable to aim for a fix in 51 nightly. 
Jim can you help find an owner for this?   Do you think it would make a good first bug?

Note, flash 23 should fix this with 49.
Hi arni2033,
Would you mind checking again if flash23 fix this?

No it didn't.
Were you just wondering or also interested in testing? You can check my result by testing "testcase 1"

Mark 51 fix-optional as there are no actions for the moment but still happy to take the fix in 51 early beta.
